I just got a new pipe for my 89 Suzuki LT250R Quad Racer what size jets do I need for my LT250R with a Paul Turner High Rev Pipe and Fat Boy2 silencer? Thanks.

 

I dont know specific jets but you can get a genuine mikuni jets at www.jetsrus.com .....good people.

 

How do I figure out what size I need? How bad will it be with the jets in it now?

 

bump still need to know how to figure out what size. No one seems to be able to tell me.

 

Well the first thing you need to do is run the bike for a few minutes then pull the plug and determine whether it is running rich or lean. Then remove the main jet from the carb so you can get the number off of it if the bike is running lean get a bigger jet if its rich get a smaller jet
